MID Server TLS 1.1

[TT3]

I got following notification form ServiceNow:

Beginning with the Now Platform^® Utah release planned for March 2023, ServiceNow MID Server offering will no longer support TLS 1.1 or below.  

TLS 1.2 and newer protocols will not be impacted, and no action is needed. However, if you utilize TLS 1.1 or below, please take a moment to review the below.  

How do we know which version of TLS is being used?

Thank you.

I found that KB to be not of much use since it is checking the TLS version supported by the instance.

The notification is in reference to MID Servers and there is a lack of information of how/where to check this in the information provided.

I have raised a support case to ask for this instead.

Please do let us know what they say. I am also curious.

I haven't explained clearly enough.  Just substitute ServiceNow's url with MID Server's url.

C) TLS1.2 --> curl -v -s https://{MID Server IP} -o /dev/null/ 2>&1

Thank you. Also, where should I execute this command? I tried in Windows cmd prompt, but it didn't gave any result on screen, neither any error.

This is what I found in my system32 folder, a file with name curl with following content:

'TLS1.2' is not recognized as an internal or external command,
operable program or batch file.

From PowerShell, execute the following command. If tls1.2 isn't supported, it should return an error.

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$response = Invoke-WebRequest -uri <MID Server URL>
